pca10000 firmware 0.9.0 throughput (Packet Drop with 0.9.0 vs No Drop with 0.8.0)

Bruce

Hi,

What's the difference between a 0.9.0 pca10000 firmware and the earlier version (0.8.0)? I noticed that the throughput with 0.9.0 on the same dongle is much less than the 0.8.0. I was able to get high through put without loosing any notifications with 0.8.0 but start seeing dropped notifications after I upgraded the firmware to 0.9.0. Firmware version is the only thing that I change in this experiment.

I set the connection interval to 20ms, with SL=9 and supervision timeout 2s and trying to push 2.5kB/s data continuously.

Thanks, Bruce

    Hi, I assume you are referring to Master Emulator Firmware (MEFW) versions.

    Version 0.9.0 of MEFW has a limitation of 1 packet per connection interval. This reduces the throughput compared to 0.8.0.

    This limitation will be lifted in a new version of MEFW which comes with next release of Master Control Panel.

    Thanks Bjørn. Yes, I was referring to MEFW.

    Since v2.1 pca10000 requires MEFW 0.9.0 to work properly, is there any other MEFW that I can use for v2.1 pca10000 to get high throughput? or is there any temporary workaround to get things going with the v2.1 hardware?

    Thanks, Bruce
